One Litre of Petrol Idle for How Long?

[BabyBlade]

Lets say car average petrol fc is 10km/l, how much time of idling in minutes will consume one litre of petrol?

 

And why would you car be idling for so long................

Idling cars are usually the sign of idling minds.

Car risk overheat if idle too long. Its not the petrol cost..but rather maintenance.. and most importantly environmental cost.

 

Imagine small kids outside near yr car.. they will be taking in the exhaust at the expense of yr comfort.

On the overheat, it is not an issue if the car is maintenance is done correctly.

Here's a cite...

 

 

Depending on your vehicle, every 10 minutes of idling is costing you between 1/10 and 4/10′s of a liter of fuel.

....taking the midpoint as 25/100 of a litre per 10 minutes that's 1.5 litres per hour

 

Here's a different cite

 

 

Table 1. Idling Emissions and Fuel Use per Second... 0.279cc

... which is almost exactly 1 litre per hour....

 

 

Here it say's a "quart every 15 minutes" - which would make it 3.5 litres per hour...Personally I think that's WAY too much (based on my personal experience)

 

Here's one cite that says 1.2 litres / hr for a 3.8 litre V6

 

Final Cite ....max seems to be around 0.36 gallons per hour with air-con running...which would be 1.36 litres per hour.

 

So my best estimate - you can assume between 1 and 1.5 litres per hour

Just off topic a bit,my 2013 Mazda 6 clocked 96 Hrs in the i-Stop[start/stop system],used a total of less than 23,000km,just changed my battery,it needs a so called Q-85 battery,costed $319.00 ,so does the start/stop system actually save $$.?Yes.. for a greener enviroment ,but for my pocket..no .a normal 2.0 or 2.5 Japanese car battery costed the most $150.00,but this Q-85 costed more than double.!

 

Assumption

a) At idle, the FC of a vehicle is 1.5 litres per hour.

b) Cost of petrol is $2.05

 

For a total of 96 hours, if with the start-stop system, the cost is 96hrs x 1.5 LPH x $2.05 = $ 295.20

 

Effectively, deducting this cost from the $319 (cost of the Q-85 battery), your loss is $23.80

If one really want to know how idle consumption is,

Very close estimation will be:

 

1) Fill the tank to the brim

2) Move slowly to the carwash behind (auto cars, don't accelerate. Manual cars, slip into 1st gear and let go clutch and don't accelerate as well).

3) idle while washing.

4) go back to pump.

 

Use the time at 2-4 and fuel use for the 2nd top up.

I think cannot like that. Isn't there a minimum. for the number of litres to top up?

I think cannot like that. Isn't there a minimum. for the number of litres to top up?

In UK I know there is a min.

In Singapore I didn't know there is.

So what if one cannot meet the minimum? Waive or have to top up?

Then if have to top up, the system itself betrays the min require fuel.

 

If I were to top up $0.20, I place back the nozzle.

Go to cashier say payment, cashier say there is a minimum purchase require say $2.00

Then I go to top up $1.80 and $0.20 previous purchase, it still lack of the minimum $2.00 per top up right.

 

Then, where is the notice for the minimum top up require?

If there isn't any notice, the seller forces buyer to top up more than require.

Like jover chew case, buy phone without warranty and top up for warranty.

[Darryn]

If not wrong I think pumps do have a minimum delivery volume,

I think it is a technical requirement of how they are set up rather than a policy of kiosk.

 

Last time I think it was 2 litres, not sure if still like that or not.

[Detach8]

I think the entire hose takes 1-2L of fuel. It's impossible to deliver you 10ml if the pump has to push 2L out into the hose before it reaches your car.

[Nicfoo]

I wonder mah since car manufacturers dont provide these details

 

Moreover I am not elites neither ASK le

 

My on board com only show max 25km/100l

 

Unless my fuel level shows the litre of petrol left in the tank

 

I am not sure if you are Elite or not, but I am here long enough to know you are known as the MCF in house ASK. LOL

[Vyeron]

Long hours of idling.. isnt it accumulating carbon?

[Nicfoo]

hmmm sleep?

 

In the day or at night? LOL

[Vhtfhwlego]

Later this week I go pump petrol and squeeze the min litre out.

If can squeeze $0.20, I will pump back pump and re-pump again to $65.

See whether the cashier black face to me or not.

And why would you car be idling for so long................

Sit inside car using 手机 surf mcf, need engine running to keep aircon cold? 行吧!? Kekeke

Else don't ask him embarrassing questions lor.

[Super7]

Long hours of idling.. isnt it accumulating carbon?

No problem. This will give him a good excuse to burn / clear carbon!!!
